The washed Duck Doyle is definitely meant to be worn in lieu of a sweater. We always style it over a woven shirt or a light knit. That's really its strength - especially as we go into Spring/Summer. With something light (like our upcoming s/s knit henleys) the Doyle will be a brilliant way to have a polished & layered look on a psychotically hot day. A big part of the "EPLA" design philosophy is to create clothing that works in warmer, more casual climates but still gives a clean and presentable look. Oh absolutely, we'll never lose that. I'm looking into the filter by size option, as I'd absolutely love to have that built in. It may or may not be a feature that can be integrated with Shopify at this time though. If not now, then most likely down the road, as Shopify rolls up improvements and extensions every few months. Should be soon - I know that they started dyeing them a few days ago. Same goes for the Hoodie & Crewneck Sure, give it a try. One thing to be conscious of is that organic duck tends to soften pretty quickly with just a few washes. That's why we used it - we wanted to have a soft, comfortable piece that mimics the feel and drape of cotton/linen. If you want this current Doyle to be starchy and straight, then you'd have to commit to dry cleaning it only as well. In that case, grabbing a pre-wash Medium should work as it's nearly 5% bigger than the post-wash item.
